When I tried to post, I got a messege "Your ability to post has been revoked due to a violation of the Terms of Service. For more details, a staff member has sent you an in-site mail.
". But no mail and no xplanation on how I broke ToS.

Your posting has been locked until we clean up what appears to be low-effort fakes you've been posting. You're not banned and will at some point have your posting given back.
